1 wait what?

it all started in 9th grade while walking home from school minding my own business while reading my favorite manga in webtoon then suddenly kaboom! i hit by a truck then blackout. i woke up in the voice of a women yelling at me to wake up, she said "wake up you idiot we're late" i still can hear that irritating voice in my head right now. I opened my eyes and see that i'm in someone's room or just what i thought at that time. i saw the woman who was yelling at me while i was sleeping right beside my bed, and she spoke again "when do you huh planning to stand up and got ready to go to the open ceremony at the academy?"

ceremony? what ceremony do mean? I replied

and that when it hit me I thought I died ,I thought that I'm already dead I hit by a truck right? but why I'm still alive? who is this person talking to me? whom room is this? and why I'm here? I'm I dreaming or what? questions in my head, and the girl spoke again "Nathan hurry up and get ready we're getting late to the ceremony mom has already packed our lunch and belongings to go to the academy. I got up to bed and walk to the small dining area while looking to the surrounding i saw a picture on the wall of me and 3 more people and I looked around again and while I'm trying to figure out what's happening a good looking woman approach me and said Nathan get ready you and your sister is getting late to the open ceremony . sister? I replied confused , yeah your sister NX you guys got accepted to the magic academy right? don't tell me you forgot about it Nathan you silly while laughing. you know what I'm so proud of you two because got accepted in the most prestigious magic school in this region got a full scholarship to the academy I'm overwhelmed of joy right now my precious children.so she is my mom then and that annoying girl is my sister so I did reincarnate to the another world and this is my life now I said to my self, but wait did my mom just said magic academy? so that mean we use magic in this world? wait whaaaaattt???
